Drying apparatus for photographic sheet material

An elongated drying chamber is provided with transport means for carrying photographic sheet material edgewise with the sheets in end-to-end relationship past a plurality of tubes that issue drying air streams. The tubes are slotted a distance equal to substantially the full width of the sheet material for complete, gentle drying by sheets of air. A common plenum supplies the tubes with heated air; the air is directed from the tube slots at a pronounced angle to the sheet surface to provide for arraying the tubes close to the surface for maximum drying effect while minimizing the danger of mechanical interference between the edges of the sheets and the slots in the tubes. The driver for the transport is housed in an enclosure between the plenum and the drying chamber; an air return duct is provided along another side to complete insulation of the drying chamber from ambient conditions

Stark ladders as tunable far-infrared emitters

A superlattice of GaAs/Ga(1 – x)Al(x)As quantum wells forms a Stark ladder under the influence of a perpendicular electric field. A two level incoherent emitter system, formed by radiative intersubband transitions between adjacent wells, is investigated as a tunable far-infrared radiation source. Intersubband transition rates are calculated at 4, 77, and 300 K for applied fields from 0 to 40 kV cm(–1). It is shown that the quantum efficiency of the radiative emission reaches a maximum at low temperatures for a field of 32 kV cm(–1). Under these conditions the emission wavelength is 38 µm with an estimated power output of 1.1 mW. © 1998 American Institute of Physics

Media Neutrality or Stakeholder Inequality? Why emerging technology requires a rethinking of the stakeholder balance in copyright law.

This paper considers a number of emerging technologies and how they challenge the underpinnings of copyright law in Australia. It draws upon the idea that copyright law must ‘balance’ the rights of stakeholders (creators of works, inventors of technology and users of works) in order to provide the most effective environment for the protection and use of works. This paper further suggests that existing copyright legislation can be divided into provisions that offer rights to creators of works (‘front end’ provisions), and other provisions that restrict the rights of users and inventors of technology (the ‘back end’ provisions). It analyses the use of ‘media neutral’ language in copyright legislation in both the front and back end provisions and argues that the creators of works have far broader rights and protections than those offered in the back end to users and inventors. Further, through an analysis of emerging technologies it is argued that this imbalance offers an environment that restricts the uptake of new technologies and fails to properly foster the protection of the rights of users of these new works and technologies
